Lance's lv 50 Dragonite was the first pokemon to OHKO Sudowoodo, ever. Ampharos's Thunder Wave was immensely helpful, letting me paraflinch for the most part through the E4. I don't remember much, but I remember Chuck's Machamp hitting my team like a truck, easily blowing past even Victreebel with DynamicPunch, though I removed No Guard with Gastro Acid. Yes, I waited that long to evolve my Weepinbell, I waited until 8th gym to evolve it, mainly due to me not knowing how to get a Leaf Stone. Karen's Umbreon was insanely annoying with Double Team. Will was blown past by Lugia, Koga met the same fate. I had to really play around Lance's Speed with Thunder Wave, and I abused the fact that his whole team was weak to Rock by praying by using Sudowoodo with paraflinching, I beat Gyara with Ampharos, and Charge-stalled Charizard.
